Mal-waif Patented Aug. 27, 1940 UNIVERSAL SPRAY DEVICE Oscar Zimmerman, South Bend, Ind., assi nor,

by mesne assignments, to Paul Summ'y, Warsaw, Ind.

I Thisinvention relates to a universal. spray device, forwateringlawns, gardens and thelike, and rGnore particularly to a novel spray head strucure. I r

One chief object of this invention isto provide a device which may be positioned immedi-. ately adjacent a building and/or a sidewalk and spray the area immediately adjacent the same without spraying the building or sidewalk, if the latter were of rectangular reentrant outline, or if the area between a building and sidewalk were of relatively narrow width.

Another chief object of the invention is to provide a spray device which may be adjusted for heavy, nroderate or relatively light volumetric spraying.

A further object of the invention is to provide a spray device which is so constructed that the length of spray can be adjusted by regulating the supply pressure of the spraying medium.

The chief feature of the invention relates to a spraying device, the parts of which are so arranged and/or provided whereby any or all of the objects set forth may be attained therewith.

Other objects and features will be set forth more fully hereinafter.

The full nature of the invention will be understood from the accompanying drawing and'the following description and claims:

In the drawing Fig. 1 is a top plan view of the invention.

Fig. 2 is a central sectional view taken on line 22 of Fig. 1 and. in the direction of the arrows.

. Fig. 3 is a diagrammatic plan view of a full circular spray efiect attained with the invention.

Fig. 4 is a similar view for quarter circle spraying when the device is positioned adjacent the vertex of a reentrant angle.

. Fig. 5 is a similar view for half circle spraying.

Fig. 6 is a similar view for three quarters cirole spraying.

Fig. '7 is a similar View for spraying a relatively elongated area having a relatively narrow width.

The invention may be suitably supported. Herein a conventional type of support includes the rod I0, pointed at I I for ground engagement. The device is furnished with water under pressure supplied by hose I2 having the threaded,

connecting member I3. Such a hose may be connected to a source of water pressure such as an out-door hydrant or the like (not shown).

Reference will now be had to the spray device head structure illustrated in greatest detail in Figs. 1 and 2. In these figures I4 indicates a somewhat elongated body portion having bore I5 therein. 'It is closed by the portion I6 having the aperture I'I therethrough. The outer end of the aperture is countersunk as at I8 and to the desired depth and angle; I

The lower end of the body portion is enlarged as at I9, to form seat 20. The interior of the enlarged portion has a tapered thread 2i for connection to the source of fluid supply as by means of fixture I3 and the hose I2. Gasket 22 provides the usual and desired leakproof seal therebetween.

The body. portion I4 and more especially the enlargement I9 herein includes a lateral extension 23, recessed as at 24 to receive the upper end of rod II] for spray head support and device positioning. From the exterior of this enlargement there extends upwardly two elongated portions 25 each of which is adapted to extend through an end link of a chain 26. These portions are upset or headed for chain anchorage.

The other end of one chain 26 is secured to an elongated blocking strip of gasket material 21 having a V-shaped groove 28 in one edge and the other edge has an angular outline 29.

UNTEDSTATES PATENT QFFICE The other end of the other chain 26 is secured to a similar strip 30 having one edge with an angular outline 3| and a straight opposite edge 32. Both strips are of resilient material and preferably are of the same thickness for a reason set forth hereinafter.

A cap member 33 having the knurled edge 34 and the lower chamfered face 35 is secured to a threaded stem 36 of lesser diameter than that of the aperture I! so that when positioned in the latter an annular discharge channel is provided.

Midway of the length of the bore I5 is a nut structure 31. Diametrically arranged wings 38 extend inwardly from the bore I5, side and end walls, as shown, and support the nut structure. The wings also act to break up any swirling action of the water so that it is radially discharged from the annular channel without swirling.

The head structure, except for the cap, threaded stem thereof, the chains and the strip gaskets, is integral and formed from white or type metal and preferably by die casting same. If the cap and threaded stem thereof are of brass, and the same is preferred, it will be clear that the device will not rust.

The taper of the countersunk seat I8 and the taper of the chamiered portion 35 may be the same or different. If difierent, the more pointed as it were, should be the seat, so that the maximum restriction of the discharge, if any, occurs substantially at the cap periphery rather than immediately adjacent the threaded stem 36.

The distance between the seat and cap determines the volumetric character of the spray, the lesser the'distance the finer the spray and vice versa. As before stated, the length of the spray is determined by the pressure supply. Of course, these two are corel'ated I j The directional character of the spray may be circular in outline or otherwise as desired. When a non-circular outlined spray effect is'desired, either or both of the gasket strips 2'! or/and may be employed by being interposed between the seat l8 and cap as illustrated-diagrammatically in Figs. 3 to 7, inclusive.

abutting is the equivalent of N ote, that the. use of two strips with adjacent portions of memselves to persons skilled in this art, all are considered to be within the broad scope of the invention, reference being had to the appended claims.

The invention claimed is:

1. A spray head structure including abody portion having a chamber therein communicating with a discharge aperture, an outwardly tapered seat defining the exterior of the aperture, the aperture being of less area than the chamber,

a chamfered control cap adjacent the seat, an

adjustable connection between the cap and body portion forregulating the spray discharge, the

body portion having a supporting portion projecting inwardly from the chamber side wall and spaced from the intake end of the aperture,

and swirl preventing vane means in said chamber adjacent the seat and extending between the plane of the aperture intake and inwardly projecting portion and integral therewith.

'2. A structure as defined by claim 1, characterized by the connection being of threaded stem and nut character, the nut portion being formed in the inwardly projecting portion of the body portion.
